Changes since 2.0.6
1. src/slmath.c: if a double precision array was passed to nint, it
   was treated as a single precision one leading to a core dump.
2. src/sldisply.c: The Is_Fg_BGR variable was re-introduced and a typo
   affecting it was corrected.
3. src/slinclud.h: Do not include malloc.h on FreeBSD (Renato Botelho
   garga at freebsd, org).
4. doc/tm/cslang.tm: Changed a couple of occurances of "unsigned char"
   to "SLtype".  (Doug Burke dburke at head, cfa, harvard, edu)
5. doc/tm/rtl/list.tm:  Documentation changed to indicate that the
   third parameters to list_append/insert are optional.  (Doug Burke).
6. src/slwcwidth.c: Added a new function to the API called
   SLwchar_set_wcwidth_flags.  This may be used to force
   SLwchar_wcwidth to 1 for double width characters.  Such a feature
   is sometimes needed for fixed fonts that treat single and double
   width characters the same.
7. slsh/lib/slshrl.sl: The readline-massage hook was interpreting
   lines beginning with a '.' as RPN.
8. slsh/lib/sldb*.sl: The debugger was not stopping upon errors
   generated by the deprecated function verror.
9. src/slparse.c: "++()" was flagged by the parser as an error, but no
   error message for it was being generated.
10. src/slang.h: #if HAVE_LONG_LONG changed to #ifdef HAVE_LONG_LONG
11. src/slsmg.c:  Return right away if SLsmg_write_chars is told to
    write 0 characters.  Also a bug fixed in the logic of this routine
    involving the test for overwriting the second half of a double
    width character.
12. src/slrline.c: Finished the UTF-8 support by the readline functions.
13. slsh/*.c: Added slsh_get/set_prompt_hook functions for setting of
    the slsh command-line prompt.  (Douglas Burke)
14. src/sltoken.c: Added additional string representations for tokens
    so that some error messages will not appear to be so cryptic.
15. src/sltoken.c: _pSLparse_error: Use the line number of the input
    stream if the linenumber associated with a token is unknown.
16. src/slparse.c: Inline arrays and lists are allowed to have a
    trailing comma, e.g., [1,2,] is the same as [1,2].
17. doc/tm/rtl/type.tm:  typo in example for atof corrected (Doug
    Burke).
18. Improvements for building on DOS/Windows (Mike Noble):

      * The various mkfiles/makefile.all now include a clean: target
      * The top-level mkfiles directory now includes 3 new files:
  
  	   A build.sh script, which auto-generates the Makefiles
	   (using mkmake) and commences a build, similar to the
	   build.bat script which was already there (and which I
	   tweaked slightly).

  	   Seed makefile.dos and makefile.sh scripts, which get copied
	   to the root of the S-Lang distro when either build.sh or
	   build.bat are run.  This makes it easier to build
	   everything at once, or clean, etc, from the top of the
	   distro.

      * A few new paragraphs in INSTALL.pc
      * In the various mkfiles/makefile.all, "CFLAGS +=" changed to
	"CFLAGS =" to avoid nmake 1.5 problems.
      * Simplified the module build targets in modules/makefile.all,
	and made it much easier to add new modules in the future.
19. Added module support for cygwin.  This involved a few minor
    changes to the Makefiles and aclocal.m4  (Mike Noble)
20. slsh/slsh.c: Brief copyright message displayed when started up in
    interactive mode.
21. src/slarray.c: Improved support for mixed-type inline arrays:
    NULLs supported (["foo", NULL]) where it makes sense, and
    type-promotion rules are used to determine the resulting type when
    concatenating mix-type arrays (["foo"], NULL, ["bar\0"]);
22. src/slrline.c: SLrline_close was not freeing the history creating
    a memory leak.
23. src/keywhash.c: Removed obsolete and unused "do_while" keyword,
    and regenerated keywhash.c
24. doc/tm/slang.tm: List of keywords updated to reflect the actual
    keywords used.
25. modules/mkfiles/makefile.all: Updated VC-specific LINK_CMD macro
    to support the changes outlines in 18 above (Dino Sangoid).
26. src/slang.c,src/slboseos.c: Added hooks for entering and leaving a
    function.  The beginning-of-statement and end-of-statement hooks
    were found insufficient to support a debugger support.  See the
    documentation for _bofeof_info for more information.
27. slsh/lib/sldbcore.sl: Modified to use the bof/eof hooks introduced
    in #26.
28. Various documentation tweaks.
29. src/slboseos.c: Changed the beginning-of-function handler to
    include the filename.
30. src/slsh/lib/require.sl: Removed the "feature not provided" message.
31. src/slrline.c: Tabs were not being expanded properly when the
    window was horizontally scrolled.  Also, the last column of the
    display is not used in case the terminal has automatic margins.
32. lib/sldbcore.sl: The debugger's "finish" command was not quite
    working as it should have.
33. lib/sldbcore.sl: Added an sldb_initialize function that can be
    overridden by the debugger.
34. src/slposio.c: Made changes to allow arbitrary objects to be
    attached to file descriptors.
35. src/sl*tty.c: Set SLKeyBoard_Quit to 0 in the init_tty routines.
36. modules/socket-module.c: A new module that defines various socket
    functions.  This required additions to the configure script and
    related files.
37. src/slstrops.c, slsh/readline.c: Removed statements that were never
    reached.
38. src/sltypes.c: foreach(X) where X is String_Type produces a
    sequence of UChar_Type objects.  This is consistent with
    typeof(X[i]).  Also added "using" forms to specify char or
    byte-semantics: foreach (X) using ("bytes"|"chars").  The default
    is byte semantics.  Updated the corresponding docs.
39. src/slang.h: Added SLang_push/pop_wchar macros.
40. src/sldisply.c: This file was failing to compile with Kanji
    support enabled.  Kanji is unsupported in slang-2.
41. src/slcurses.*: Alt-character set handling was not working.  Once
    again, I strongly encourage you to modify your programs to use the
    native SLsmg routines instead of the partial curses emulation hacks.
42. slsh/lib/sldbsock.sl: New file to implement socket-based debugger.
43. slsh/scripts/sldb: Added --pid <pid> option for debugging a
    separate process via the socket-based debugger interface.
44. src/slang.c: If a try-finally block contained a return statement,
    the function would sometimes continue after the finally block.
45. modules/termios-module.c: Added tcget/seti/ospeed functions for
    setting baudrates of termios structures.  Also added CRTSCTS
    constant to the module.
46. src/slclass.c: If an application calls SLang_pop_mmt with a
    non-MMT type specified, a SL_Application_Error exception will be
    generated.
47. src/slang.c: A misplaced return statement was introduced by #44
    above.
48. src/slparse.c: Allow the "finally" keyword to be followed by a
    colon, e.g., try foo; finally: bar;
49. src/sltoken.c,slang,c: "Dollar" and long-longs were not being properly
    handled in byte-compiled files.
50. src/test/Makefile: Changes were made to test byte-compiled
    versions of the test scripts.
51. modules/socket-module.c: added #include <time.h> to get it to
    compile on mac osx.
52. src/slmath.c: The data field was not properly used by the nint function.
53. modules/select-module.c: Call SLang_handle_interrupt when the
    select system calls gets interrupted.
54. src/slposio.c: Add == and != operators to FD_Type objects so that
    fileno(stdin)==fileno(stdin) works as expected.
55. src/slarray.c: wherefirst and wherelast were not working with
    empty arrays.
56. src/slmisc.c: SLang_guess_type was failing on numbers containing a
    leading '+' sign.
57. src/slimport.c: The name of the SLANG_MODULE_PATH environment
    variable may be changed in src/Makefile.
58. src/slrline.c: Added a delete-to-beginning-of-line (delbol)
    function and bound it to ^U.
59. slsh/Makefile.in: $(CFLAGS) added to the final link line. (Nelson
    H. F. Beebe)
60. src/slmath.c: Avoid the use of function pointers to standard math
    functions to support a wider range of compilers.
61. autoconf/aclocal.m4: IRIX compilers do not require "-K pic"
62. autoconf/configure.ac: Probe for socklen_t.
63. */Makefile.in: Added support for the $LIBS env variable
64. src/slerr.c: Added fflush(stdout) to SLang_vmessage.
65. slsh/lib/sldbcore.sl: The eof hook was improperly handling the
    debugger step.
66. src/slarray.c: Optimization added for index-array operations on
    double, float, and int arrays.
67. src/slarith.c: Optimization added for boolean operations between
    [U]Char_Types.
68. lib/structfuns.sl: Typo in the documentation corrected (Doug Burke)
69. lib/*.sl, lib/tm/*.tm, lib/help/*.hlp: Documentation for the
    functions in *.sl has been moved to *.tm and integrated into the
    help system.
70. src/slwclut.c: a missing "default" label in a switch statement was
    causing invalid character class specifiers to pass.
71. src/slang.c: Optimization added for struct method calls.  In
    addition, linenumber information was propagated for such function
    calls to permit better interaction with the debugger.
72. slsh/lib/profile.sl: profile_on was not being called with an
    argument.
